DRIVE SYSTEMS
5 - 12 Single Stage Snowthrower Service Manual
In the 1999 manufacturing year, some models were
built with the spring loaded idler system and some with
the handle controlled rotor engagement. Although the
pulleys and idler on Powerlite models are in the same
locations and function the same as the older models,
the belt is different. All Powerlite’s and some CCR
1000’s use a conventionally shaped V belt instead of
the flat multi-grooved belt used on older models and all
other CCR models.
Spring Loaded Idler System
To access the drive system, remove the belt cover on
the left hand side of the machine. The belt drive
system is now fully exposed. The belt is routed as
shown in Figure 84.
Figure 84 0623-06
To remove the belt, pull the idler pulley upward and pull
the belt out from under the idler, release the idler
slowly. The belt can now be rolled off the rotor pulley.
To replace the belt, route around the engine pulley,
then around the rotor pulley, then finally pull the idler
upward and locate the belt under the idler. In order for
the system to function, the idler pulley must be free to
rotate and the idler arm must be free to pivot (Figure
85). If the idler pulley can not take up the slack in the
belt, either the belt is badly worn and must be replaced
or one of the pulleys has failed.
